Application ined July si,

To all whom t may concern:

Be itl lmoivn that l, Em Bno'rrinns, a citizen ci" the United States, residing at Lynn, in the county of Essex and State `of Massachusetts, have invented, certa-in Improvements in Uppei'-liilliiig lliachines, of Which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the draivings indicating like parts in the several figures This invention rela-tes to upper pullingmachines and is herein shown as embodied in a machine particularly designed for pulling an upper preliminarily to stretch it and draw it into approximate contorniity to the contour oit' a last prior to the present tion ot' the shoe to a pulling-over nuuihinerv lt will he understood, however, :troni a consideration ot the construction and mode ot operation oit the illustrative machine that in many oit its features the invention is not .restricted in utility to machines for thus pertermino` a preliminary upper pulling' operation, hut in its broader aspects is ot general applicability to machines for pulling uppers on lasts.

It is a Well recognized Vtact that under some manufacturing conditions, as tor example where the upper is so cut that it is small for the last, or Where the last is shaped in a peculiar manner, the hest results in the pulling-over of' the shoe and in the unal shaping; of the shoe require that the upper he pulled and stretched more or less lietore the shoe is presented tothe pulling-over machine. By seizing; the upper at the toe end ont the last and 'iulhng;` it lengthwise ot the last the margin oi' the upper at the toe`r it the upper is comparatively short, may he so located :is to permit the toe gpiikiper ot the pulling-over machine readily to engage it when the shoe is presented to thatiuachine, and such a preliminary lenn'tln 3, pull upon the upper also insures hotter esults in the .tiual shaping of the upper about the. heel end portion ot the last. Similarly, hy seizing; sind pulling' the upper at the ojiposiief sides ot'the toreparhy the margin may he more conveniently located 'tor present tion to the side Q'ripiiers ot' the pullin;;'o\y machine, and by thus drawing the upper down to the wood of the last back of the toe prior to the final pull at the toe and the sides a better [ina-l shaping of the :torepart oit the upper is 5 insured. An object et' this invention, among 191s; serial No. 246,523;

others, is to provide an improved machine adapted :for use in performing such preliminary pulling and stretching operations upon uppers ivitha vievv to simplitying` the constructionr of such macliines, rendering them more convenient 'for use,vand improving the quality of the Work.`

A feature of the invention consists in `a novel organization of means for pulling an upper preliminar-ily to stretch and position it' on a last and for then releasing it in an unsecured condition, the machine herein shown lia-ving means lor applying` a pull to the upper substantially simultaneously at the toe end and at opposite sides ot the shoe and 'tor tensioning the upper variahly as determined hy the operator during the progress of the upper pulling operation. The illustrative construction comprises grippers for engaging the upper respectively at the toe and at opposite sides ot' the toi-eport, with treadle operated means for causing all of said tgrippers to close upon the upper prior to the pulling oi' the upper either longitudinally or transversely and tor then moving,` the last relatively to the `strippers to pull the upper to an extent yariahly determined hy the operator in' accordance with the condition oli the particular shoe. The use oi' this construction insures that the upper shall he engaged hy thel grippers at the precise points desired at the sides as well as at the toe end ot the last, and contributes to uniformity ot results en ivork Where the margin ot the upper needs to be pulledto substantially the same extent at the toe and the sides.

A further feature oli the invention consists in novel means tor positioning' a shoe and tor al'iplying' a pull to the upper substantially simultaneously at the toe and at opposite sides, so organized as to permit the operator to varyv at will the relation l'ietiveen the lon le'itudiiial tension and the transverse tension as the pulling oli the upper progresses, thus Yfacilitatingi` the proper stretching' and shapiup` ot uppers which reduire `dilierent`treatnient at the toe and the sides respectively; the iii-schine herein shown having,Y shoe'positioninnl means so constructed as to permit the operatory to svi/'ing' theshoe to proportion as desired the longitudinal pull ot the toe gripper to the transverse pull ofthe side grippers. Theconstruction shown also afiords, as an additional Jfeature provision for lateral swinging movement ot' the last'to effeet a relative adjustment. between the lest and the upper asE 'li'er exemple, to straighten the tip seam7 or to effect relative ai'ljustnient between the toe gripper and the opposite sides ot the last.

A Vfurther 'feature ot' the inre'itiom as applied to au organization coniprisinej a shoe rest 'which is moved to effect a pull on the upper7 consists in novel means tor cousine; the upper to be gripped in time relation to the movement ot the rest. Vlhe construction shown comprises means movable with the shoe rest in the saine direction for relativelyY i'orcing the `gripper jaws to closed position. In the illustrative construction, moreover, yieldable inea-ns is provided whereby the upper is caused to be gripped with pressure increasing` in proportion to the extent of movement ol the shoe rest 'tor eiljecting' the pull, and still another 'feature resides in novel means for increasing' the gripping pressure on an upper iu piwnyortioii to the strength ot the pull.

Further tentures of the invention are to be recognized in a novel gripper construction, in a novel provision toi.' relative ad justment of different grippers, and in various details of construction and combinations of parts, all of which will new be described with reference to the accompanying drawings and pointed out in the claims.

In the drawings,-

Figure l is n plan view ot a machine in which the invention is embodied;

Fig. 2 shows the machine in side eievzition; o

Fig. 3 illustrates the relation of the rgip pers and the shoek bottom rest to the shoe during' the upper' pulling operationnl one ol" the side lggrippers being' omitted and the toe gripper sectioned to reveal its interior construction Fig'. 4 is a detail view o'l a portion oll the gripper closing' meansv` and Fig'. 5 illustrates the relation ot the mechanism shown in Fig'. 4l to the shoe, bottoni rest and the gripper closing;- rods.

The machine comprises a frame 2 whichl in the construction shown, is particularlyv designed. to be mounted upon a work bench` the upper portion ot the treme having' a horizontal table portion lf upon which are mounted a toe gripper and side gripper-s comprising' .respeetiveljvY gripper casing-s o and 8 which are maintained iu substantiall ri gid relation to the treble f1; du ring; the upper pulling' operation. Projecting upwardlyY through a hearingr iu the table 4i und through a lower bearingT l0 in a horizontal portion of the frame 2 is a rod 152 the upper end eln which is roughened for engagement with :i sole or innersole upon the bottom of' a last. the rod being; thus constructed and arranged to provide a bottoni rest for the shoe. fis shown in Fig. 3, the bottoni rest is arranged in such relation to the grrippers as to engage the bottoni of the shoe at the 'iorepart only, while leaving` the shoe tree to be swung' vertically or moved laterally in relation to the rest and the grippers. spring 14k mounted upon the rod l2 is arranged to bear at its upper end against the table 4l and at its lower end against a bracket 1G secured to the rod, the spring thus holding' the rod normally in its lowermost position determined by engagement of the bracketl with the stationary bearing' 10. ln order to cause the rod 1n to elevate the shoe7 the machine is provided with a lever 18 pivoted on the frame with one arm bearing` upwardlj,T against the lower end of the rod and with its other arm connected by means of a link 2O to a tremllle not shovi'n in` the drawings.

To each of the gripper casinos is secured rigidl7 a gripper jaw QL and pivoted on the easing' i s a ifo-operating iaw 24tfor swine-ingr movement toward und from the rigid jaw. Mounted slidably in each ol the gripper cus ine's 6 and S .is a closing rod 2G which extends downwardly in parallel relation to the red lf2 and to the direction of the pull of the gripper upon the upper and carries at its upper end a bracket 28 upon which is mounted a roll 30 in a slot 32 formed in a lateral extension or shank ot' the pivoted gripper jaw 9.1i. It will be evident b v reference to lli 3 that the roll 30 and the slot 32 are in such relation to the gripper jaw as to cause the jaw to be swi'ing toward the lined jaw 2Q into position to Igrip the upper by an upward movement toward und relatively 'to the :gripper jaws ot the closing rod 26. AFor imparting; such movement to the several closing' rodsthe bracket 1G provided with a. toiwvardlv7 extending' arm 34 provided with a slot 36 throufrb which the closing' rod 26 o'lt the toe ygripper extends,r and with laterallv extending' arms 3S provided with slots i0 to receive the closingv rods of the respective si de `e'rippers. Flach ol the closing' rods, as shown by Fins, 2 and 5, is reduced in diameter below the table 4land. is encircled bv a spring which bears at its upper end against the shouldered portion ol: the rod thus provided and bears at its lower end upon a washer 44 which rests upon the corresponding' arm ot the l'n'arlr'el' lil. Pw low the bracket eaeh ot the rods carries a limiting' collar 4:6. lt will be evident tlm! in the use ot this construrtion upward more nient o?? the rod lf2 to elevate the shoe rela tiifel;T to the lQrippcrs imparts l'l .'ougrh the bracket i6 and the springs 4:2 closing more ment to the rods 2G and to the pivoted zgripper jaws, and that bv the compression of the springs 42 the gripping; pressure ot' the sever-el gripper jiztws upon the upper increased in proiiortion to the extent of upward movement o'l the shoe and the resultpnll upon the upper.

ln order to render thez machine effective in the manner desired upon dillei'ent sizes oic shoes, the toe gripper is adjustable relatively to the rest 12 in directions lengthwise ot a shoe7 the casing 6 of the gripper being flanged for sliding movement in guideways 48 on the table 4 and secured inadjusted position in any convenient manner, as for example by the use of a clamping screw 50. ln order to permit suoli adjustment ot' the toe gripper the table 4 is provided with a slot 52 in substantially parallel. relation to which theslot 36 in the arm 34 of the operating bracket 16 extends, thus insuring cooperative relation between the bracket and the gripper closing rod in different adjusted positionsof the gripper. ln Order to provide `tor adjusting movementof the side gripper-s toward and from a shoe the side gripper casings 8 are carried by arms which are mounted upon upright pivots 56 .on the table 4 located approximately adjacent to the toe end et the shoe. Slots 5S in the table 4 are curved substantially about the pivots as centers -to permit the adjustment et the grippers, the slots 4() hereinbe- 'iore referred to in the bracket 1G extending in substantially parallel relation to the slots 58. Springs G0 mounted on the pivots 56 tend to swing the gripper carrying` arms inwardly toward the shoe rest, and cach arm carries a pivoted spring` pressed pawl 62 mounted adjacent to its handle portion 64 and arranged to engage the teeth ot a rack GG on the table 4. Each oic the side grippers may thus be readily adjusted at thevwill ot the opeiator toward or trom the shoe rest independently ofthe other and held in adjusted position to conform to the dililerences in width and shape oit dil'llerent shoes. lt will be evident, moreover, that the shoe engaging portions ot the jaws oi the side grippers incline convergently toward the toe end ot the shoe in directions substantially or approximately parallel to those portions of the edge olf the shoe bottom which are opposite to the portions oit the upper engaged by the gi'ipoers, and that as the side grippers Vare adjusted for slices of diiterent widths the inclination of the jaws is likewise cliianged by reason ot the swinging` movement oit the grippers about their pirots 5G to insure substantial conformity between the positions ol" the gripileis and the shapes ot the difiere-nt shoes` ln the operation oit the machine the shoe is presented with the bottom ot the torepu rt resting` upon the upper end ol the rod 12 undy with the edge ot the upper projecting.:` within the open j aws ot' the several grippers which project upward sutiiciently relatively to the shoe restto the margin of the upper evenk ii. the latter is out compara-tively small 'for they last, When the shoe has been thus ypositioned the operator depresses the upper with increasing pressure. upper pulling operation progresses7 the opeffect at yany time relative tween the longitudinal andthe transverse treadle and raises the rod 12 against the tension ol its spring 14u ln the initial nio-fe,- ifnent oit the rod the bracket 1G, through 'the closing springs 42 and rods 26, imparts closing movement to the pivotcd gripper 24 tolcause the jaws to grip the margin oi: the ripper. During` the 'continued upwari'l movement oit the rod l2 and consequent ele vationof the shoe relatively to the grippers, the upper is pulled by ,the grippers both. lengthwise and transversely over the last? the increasing compression. ot the springs 42 meantime causing the grippers to hold the erator is enabled, by swinging the shoe rertically about the rod 12 as a tuleruin, to increase or diminish the :torce of the pull of the toe `gripper upon the upper relatively to the pull oit" the side grippers in order to 'tension as conditions demand and to insure that the upper shall be pulled and stretched opposite sides ol' the last, and also to effect ar relative adjustment oit the last and the upper tor the purpose oit straightening the tip seam betere the shoe is subjected to the final pulling-over operation.

lila ing stretched the upper inthe manner required to insure the proper presentation oi themargin to the grippers ot'the pullingover machine and to contorni and adjust the upper pi'eliniinarily to the contour oit the lastptlie operator may place his hand upon the shoe iii such manner as to hold the upper bstantiallg,r in the desired positioiu and by releasing the treadle he then permits the grippers to be opened by reverse movement oit the closing rods and the shoe rest 'to be returned to its starting position by the action ot the spring- 14. The shoe, while held in this manner by the operator7 is immediately presented to a pullinSr-over machine and pulled over and. fastened in the usual manner. n
